recommendations on hifi sound card to rival modded X-Meridian

post #1 of 8
Thread Starter 
Hi all.

In my HTPC I currently have a modded Auzentech X-Meridian. Upgraded opamps, upgraded capacitors, and some circuits bypassed. I followed a thread on this forum a few years back and had an electronics professional carry out the work.

This card sounds absolutely fantastic. Way better than stock and it blows the pants off most other computer sound cards I have heard.

Unfortunately now after several years the subwoofer output on the card seems to have failed. So I think it is time to buy a new soundcard frown.gif

Can anybody advise what is the best 5.1 (or higher) channel sound card available at the moment, either one that is going to have fantastic analog outputs out of the box, or is readily able to be modified? If the latter it would need to be something where the community has gotten all excited like the 1st gen Meridian - with somebody posting diagrams etc of what to do.

Cost is not really an object here ... I value quality sound.

Thanks in advance for your advice smile.gif

bump .....

any advice would be much appreciated!

(I've tried optical SPDIF and HDMI audio feeds to my receiver, and neither of them are a patch on the modded X-Meridian, even with the missing sub channel)

I would really look at the latest usb DAC's. With an Pre/Pro or receiver that can process 24/96 pcm, that can be sonic nirvana. I have a V Link musical fidelity running off my HTPC hooked up to my Sony TAE9000 preamp and my music collection has never sounded better. I would think in the D to A stage, it would be pretty trying to get all that quality out of a PCI card vs an actual component.

The Meridian had better DACs than your receiver? That seems counter-intuitive.

The meridian had an AKM AK4396 DAC, 120db SNR. Not bad overall and could definitely be a lot better than a low end or mid-range receiver.

OP, as a replacement you might want to look at the Asus Xonar ST with H6 board if you have a PCI slot. Great card. Has a Burr Bown PCM 1792A DAC, 127db SNR FYI.

Thanks, that card looks really good.

I don't really understand why it sounds so much better. But I have tried every form of digital input into my Pioneer VSX-Ax4Avi (this is a decent receiver, has the Air Studios Monitor certification) and the only one that ever sounded any good was SACD over a firewire cable from a Pioneer DVD/Sacd player. That had a clock synchronization feature which reduced jitter. As I suspected that jitter over the digital inputs was the cause of the quality difference I purchased a USB spdif converter with its own (purportedly) high quality clock and that made exactly ZERO difference to the quality of the sound when processed by the receiver.

The funny thing is that even on the analogue inputs I think the receiver must be converting back into digital for MCACC processing? This is the setting that adjusts the frequency outputs and delays etc to optimise the speakers to the room. This IS counter-intuitive.

Honestly we are talking about a WORLD of difference here.

The problem is that I use the HTPC for multi-uses. Movies, music, and games. I'm sure that a USB dac would provide the best 2 channel music output but I don't want a setup where I have to constantly change settings.

Any idea which would be better, the CLARO halo XT or the Asus Xonar ST with H6 board?

Both are good but from everything that i have read the Xonar is supposed to be slightly better than the Halo XT.
